Eco OLED First Applied to Galaxy Z Fold3
Samsung Display has developed an OLED panel for smartphones that cuts power consumption by 25 percent compared to previous ones. It was first applied to the Galaxy Z Fold3, a foldable phone that Samsung Electronics unpacked on Aug. 11.
The company announced on Aug. 16 that it has developed a new panel structure that blocks external reflection from displays and registered its brand name of “Eco OLED” in major countries. It features a 33 percent increase in light transmittance and a 25 percent cut in power consumption.
The new stacking structure has improved the light efficiency of polarized plates. Polarized plates are opaque plastic sheets that increase the visibility of OLED displays by preventing light coming from the outside of panels from contacting electrodes. However, when light passes through a polarization plate, its brightness falls by more than 50 percent.
"We have succeeded in internalizing polarizing panel functions for the first time in the industry,” a Samsung Display official said. “We have recently applied for registration of Eco OLED as a trademark in seven countries, including Korea, the United States, the United Kingdom, China and Japan.” Eco OLED means a low-power eco-friendly component.
This technology was loaded into Samsung Electronics' new foldable phone, the Galaxy Z Fold 3. It also contributed to the development of under display camera (UPC) technology that hides camera holes in display screens. "As the light transmittance of displays has improved, we were able to secure UPC-based technology by delivering more light to camera modules at the bottoms of the panels."
